Abstract

The invention discloses a flame-retardant communication cable. The flame-retardant communication cable comprises conductors, insulating cable cores and nylon rope cores. Each conductor is formed by stranding a plurality of silver-plated soft copper wires, and polyethylene insulating layers are wrapped on the conductors in an extruding mode to form the insulating cable cores. An aluminum tape sub-shielding-layer is wrapped on every two corresponding insulating cable cores in a lapping mode after the two insulating cable cores are oppositely stranded together to form a main cable core. A plastic film is wrapped on the five main cable cores in a lapping mode after the five main cable cores are combined together to form a wrapping tape layer. A master shielding layer formed by braiding a plurality of silver-plated soft copper wires is arranged outside the wrapping tape layer. An outer sheath layer made of black flame-retardant polyvinyl chloride materials is wrapped on the master shielding layer in an extruding mode. A drainage wire is arranged between the wrapping tape layer and the master shielding layer. The five nylon rope cores are arranged between the five main cable cores. A center cable core is arranged in the center of the cable. The flame-retardant communication cable is good in tensile performance, flexibility and flame retardance.

Description

A kind of fire-retardant communication cable
technical field
The present invention relates to a kind of fire-retardant communication cable, belong to technical field of electric wires and cables.
Background technology
In communications industry, can light the general electric wire that is applied to for being communicated with various communication apparatus, this has proposed some special requirements to communication cable, as tension, glow etc.
Summary of the invention
The invention provides the fire-retardant communication cable that a kind of tensile property is good, flexibility is good, fire resistance is superior.
The solution of the present invention is as follows: a kind of fire-retardant communication cable, comprise conductor, insulated wire cores and nylon wire rope core, and conductor, with adopting many silver-plated soft copper skein silks to close, extrudes polyethylene layer outward at conductor and forms insulated wire cores; After two insulated wire cores pair twists, wrapped aluminium strip sub-shield forms master core, the wrapped formation belting layer of wrapped employing plastic film after five master core combinations, many silver-plated soft copper silk braided overall-shielding layers of the outer employing of described belting layer, described total screen is extruded with the external sheath layer that black flame-retardant pvc material forms, and between described belting layer and total screen, a drainage thread is set; Between five described master cores, five nylon wire rope cores are also set; Cable center also arranges Yi Gen center core, and by three insulated wire cores, wrapped polyurethane belting layer, metal screen layer form described center core successively outward.
Further, silver-plated soft copper silk quantity >=10 piece that described conductor adopts, 10~16 times of twisting pitch.
Further, the monolateral insulation thickness of described insulating barrier is 0.6mm, the thinnest point >=0.55mm of insulation.
Further, the monolateral thickness 3.0mm of described external sheath layer, the thinnest point >=1.8mm.
Tensile property of the present invention is good, flexibility is good, and cable core is filled and adopted tension rope to fill, and ensures and improved the tensile property of cable; The polythene material that insulating material of the present invention adopts, its oxygen index reaches more than 32, therefore its fire resistance is superior; Tensile strength reaches 25~34Mpa; Electrical insulation capability is good, and its disruptive field intensity reaches 40MV/m, and percentage elongation reaches 600%; Sheath material of the present invention adopts flame-proof polyvinyl chloride material, and its fire resistance is superior, and oxygen index reaches more than 35, its long-range circumstances working temperature reaches-15~70 DEG C, has ensured the flexibility of cable, its hot strength >=25Mpa simultaneously, elongation at break >=350%, tearing strength >=65KN/m.
brief description of the drawings
Fig. 1 is structural representation of the present invention.
embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of fire-retardant communication cable, comprises conductor, insulated wire cores and nylon wire rope core, and conductor 2 use adopt many silver-plated soft copper skein silks to close, and extrude polyethylene layer 3 and form insulated wire cores outside conductor 2; After two insulated wire cores pair twists, wrapped aluminium strip sub-shield 4 forms master core, the wrapped formation belting layer 5 of wrapped employing plastic film after five master core combinations, many silver-plated soft copper silk braided overall-shielding layers 6 of the outer employing of described belting layer 5, described total screen 6 is extruded with the external sheath layer 7 that black flame-retardant pvc material forms, and between described belting layer 5 and total screen 6, a drainage thread 8 is set; Between five described master cores, five nylon wire rope cores 9 are also set; Cable center also arranges Yi Gen center core 1, and by three insulated wire cores, wrapped polyurethane belting layer, metal screen layer form described center core 1 successively outward.
Silver-plated soft copper silk quantity >=10 piece that described conductor 2 adopts, 10~16 times of twisting pitch.The described monolateral insulation thickness of insulating barrier 3 is 0.6mm, the thinnest point >=0.55mm of insulation.The monolateral thickness 3.0mm of described external sheath layer 7, the thinnest point >=1.8mm.
Tensile property of the present invention is good, flexibility is good, and cable core is filled and adopted tension rope to fill, and ensures and improved the tensile property of cable; The polythene material that insulating material of the present invention adopts, its oxygen index reaches more than 32, therefore its fire resistance is superior; Tensile strength reaches 25~34Mpa; Electrical insulation capability is good, and its disruptive field intensity reaches 40MV/m, and percentage elongation reaches 600%; Sheath material of the present invention adopts flame-proof polyvinyl chloride material, and its fire resistance is superior, and oxygen index reaches more than 35, its long-range circumstances working temperature reaches-15~70 DEG C, has ensured the flexibility of cable, its hot strength >=25Mpa simultaneously, elongation at break >=350%, tearing strength >=65KN/m.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection scope of the present invention.
